The Lunar Hatch project aims to blast eggs into space, hoping that aquaculture will provide protein for astronauts on missions At first glance, there doesn’t seem to be anything special about the sea bass circling around a tank in the small scientific facility on the outskirts of Palavas-les-Flots in southern France. But these fish are on a mission. When fully grown, they will produce offspring that will be the first to be launched into space as part of a scientific project called Lunar Hatch that is exploring whether sea bass can be farmed on the moon – and eventually Mars – as food for future astronauts.
